“…The AHP, introduced by Saaty (1980) [42], is known for its simplicity in principle and dependable theoretical foundation. Abundant practical cases have demonstrated the significant applicability of AHP in effectively addressing complex multi-objective com-petitive decision-making problems [100][101][102][103][104]. The AHP generally involves the following three steps:…”

Geohazards pose significant risks to communities and infrastructure, emphasizing the need for accurate susceptibility assessments to guide land-use planning and hazard management. This study presents a comprehensive method that combines Variable Weight Theory (VWT) with Analytic Hierarchy Process (AHP) to assess geo-environment vulnerability based on susceptibility to various geohazards. The method was applied to the Pearl River Delta in China, resulting in the classification of areas into high vulnerability (5961.85 km2), medium vulnerability (19,227.93 km2), low vulnerability (14,892.02 km2), and stable areas (1616.19 km2). The findings demonstrate improved accuracy and reliability compared to using AHP alone. ROC curve analysis confirms the enhanced performance of the integrated method, highlighting its effectiveness in discerning susceptibility levels and making informed decisions in hazard preparedness and risk reduction. Additionally, this study assessed the risks posed by geohazards to critical infrastructures, roads, and artificial surfaces, while discussing prevention strategies. However, this study acknowledges certain limitations, including the subjective determination of its judgment matrix and data constraints. Future research could explore the integration of alternative methods to enhance the objectivity of factor weighting. In practical applications, this study contributes to the understanding of geo-environment vulnerability assessments, providing insight into the intricate interplay among geological processes, human activities, and disaster resilience.

“…During sedimentation process, these rocks acquire different bedding planes or lamination and the study area is located in active zone of earthquake which further increases the formation of fractures in the hydrogeology (SAPCC, 2017; Rao, 2018; Hauhnar et al, 2021). The properties and the dip orientation of theses laminations have a signi cant effect on the properties of the rock in terms of stability and strength (Hauhnar et al, 2021;Biswas et al, 2023). They are greatly affected by motion of water in the presence of abrasive objects such as clay and sand.…”

“…The acute shortage in water supply and rise in demand is a problem generated by the recent reports of decrease in water discharge and drying up of these springs (Filippini et al, 2024;Pandit et al, 2024;Bhat et al, 2022; EFCC-GoM, 2020; Sailo et al, 2022). The water shortage may be caused by a number of factors such as rapid urbanization, agricultural practices, localised development of infrastructures and climate change (Daniel et al, 2021;Biswas et al, 2023;Ghimire et al, 2019;Ozdemir, 2011). The amount of moisture present within the soil decreases at "low ow" period occurs where streams and spring dry up bringing the moisture content of soil and water table decreases.…”

The North Eastern part of India compromises of hilly slopes and ridges. The main source of water is of river, streams, rainfall and springs. Due to change in environmental variables, many springs and streams are drying up as discharge decreases. A lithological study shows the area to consist of clay, silt, shale, siltstone and sandstone where porosity is low leading to low yielding capacity. Hydrogeological and geochemical composition studied represents the water within this region as immature and major ions composition shows Na+>Mg2+>Ca2+>Mn2+>Fe2+>K+ in cations and anoins HCO3->Cl->SO42->NO3->PO43-. The mineral saturation indices constructed using PHREEQC showed supersaturation with dolomite, siderite and vivianite. The hydrogeochemical formation mechanism using Gibbs Diagram and Piper diagram suggested rock weathering type. Principal Component Analysis (PCA) was performed as a multivariate analysis to determine the correlation between different components of hydrogeochemistry. The assessment of springwater quality using water quality index (WQI) shows good quality for most of the samples. A conceptual recharge model was the constructed anticipating mountain front recharge as major recharge of spring water. The springwater hydrograph was modelled using Maillets. It was observed that two types of flow, firstly the initial larget slope corresponding to conduit flow and secondly smaller slope to the diffuse flow was system. Thus the main mechanism of recharge in the hilly regions of West Phaileng was attributed to the mountain front recharge which is influenced by faults and fractures.

“…As a result, the preservation and efficient use of groundwater have gained significant attention in recent years, because surface waters are insufficient to meet human demands [3,4]. Groundwater is not visible to the naked eye, making it challenging to map this resource [3].…”

Groundwater management in the Jinan Spring basin is hampered by its complex topography, overexploitation, and excessive urbanisation. This has led to springs drying up during dry seasons and a decrease in discharge in recent years. GIS and the AHP were employed to delineate groundwater potential zones using eight thematic layers: slope, geology, lineament density, topographic wetness index (TWI), rainfall, soil, drainage density, and land use/land cover (LULC). The model’s accuracy was assessed by comparing the findings to basin groundwater observation well data. We found that 74% of the observations matched the projected zoning. Further validation utilising the receiver operating characteristic (ROC) curve gave an AUC of 0.736. According to the study, 67.31% of the land has a good GWPZ, 5.60% has a very good one, 27.07% is medium, and 0.03% is low. Heavy rains throughout the rainy season raise water levels. Dry weather lowers water levels. This study’s conclusions will protect groundwater from climate change. Integrating hydrogeological data, GIS, remote sensing, and AHP approaches maximises data use, improves groundwater potential zone delineation, and promotes sustainable groundwater resource management decision making. This integrated method can help land use planners, hydrologists, and policymakers find optimal locations for water supply projects, establish groundwater management techniques, and reduce groundwater risks.
